As part of their ongoing DRM-Free Summer Sale, GOG have today put every Ultima game in their catalogue (including the Underworlds!) on sale for up to 80% off.

If for whatever reason you haven’t yet added an Ultima to your GOG library (apart from the ones you get for free: Akalabeth, Ultima 4, Savage Empire, and Martian Dreams), you can do so today for a mere $7.14 USD.
